Quick Introduction and Help

My name's Alex, I'm 18, and I'm interested in programming out of necessity. This site was the first that popped up with the Google search "programming forum", thus the reason I found it.

I help run a website with a few other friends, and I'm in charge of designing a module. We were going to ask someone to program it for us, but it would cost upwards of 5000 dollars, money we don't have.

So, if someone could direct me somewhere, or anywhere that would be helpful, that would be awesome. The module will have to utilize wiki software, and some sort of database. If anyone thinks they can help, I can elaborate further via PM.
